Mahesh,
please tell us what you want to do.
If you want to create a new network namespace, it is not mandatory to
use clone. The following program will create a new network stack and all
new processes will inherit this network namespace.
#include <sched.h>
#include <stdio.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
pid_t pid;
if (unshare(CLONE_NEWNET)) {
perror("unshare");
return 1;
}
pid = fork();
if (pid < 0) {
perror("fork");
return 1;
}
if (!pid) {
execl("/bin/bash", "/bin/bash", NULL);
perror("execl");
}
return waitpid(pid, NULL, 0);
}
I recommand you read the documentation

Thanks
